Zero-knowledge proofs (ZKPs) have come a long way from theory to real-world applications like blockchains and private transactions. We’ve been busy auditing various ZKP implementations and developing tools to improve circuit safety and security. In this blog post, we’ll explore how vulnerabilities can crop up in SNARK systems and the current state of tools designed to spot these issues. From circuit bugs to the often-overlooked frontend and backend layers, we cover how various analysis techniques and formal verification approaches are evolving to ensure robust ZKP systems. Dive in to discover the potential and current challenges in ZKP security!

We’re excited to share that our programming language, noname, now supports R1CS, making it easier to write zero-knowledge (ZK) circuits and deploy them on Ethereum using SnarkJS. This update introduces an alternative to the common Circom language, with a simple and intuitive syntax inspired by Rust and Golang. In this post, we illustrate how to deploy a noname-based Sudoku circuit on Ethereum, demonstrating core benefits like proving a solution’s correctness without revealing it. Dive in to explore how noname could potentially unify the fragmented zkSNARK ecosystem and simplify your circuit writing process!

We recently teamed up with Lighter to dive deep into their custom ZK circuits used for a verifiable orderbook matching on a Layer 2 exchange. Our findings show solid and well-structured code, thanks to their cooperative engineering team. The post gives a fascinating look into how Lighter’s ZK rollup ensures valid state transitions on Layer 1 through zero-knowledge proofs and the innovative structure of their order book matching process. It explains the roles of the main operation and exit hatch circuits, while also touching on how users can exit in emergencies. It’s a great read if you’re curious about how these systems maintain security and efficiency in decentralized finance.

We’re teaming up with StarkWare to enhance Ethereum’s scalability using an exciting tool called the EVM adapter. This innovative open-source project takes proofs from the Stone Prover and makes them verifiable on Ethereum, showcasing the power of Cairo bootloader programs for Layer 2 scaling. By diving into our collaboration, you’ll get a glimpse of StarkNet’s ability to streamline transactions efficiently and how our joint efforts are driving this tech forward. Plus, our Stark Book offers a deeper technical dive for the curious minds!

In February 2024, we dived into a security audit of Darkfi’s built-in contracts and circuits, putting them under the microscope to ensure everything checks out. Curious to know what we discovered while navigating the public Darkfi repository? Check out our full report for insights and findings.
